AimsEpisodes of acute heart failure (AHF) may lead to end-organ dysfunction. In this post hoc analysis of the Relaxin in Acute Heart Failure trial, we used the MELD-XI (Model of End-Stage Liver Dysfunction) score to examine hepatorenal dysfunction in patients with AHF.Methods and resultsOn admission, the MELD-XI score was elevated (abnormal) in 918 (82%) patients, with 638 (57%) having isolated renal dysfunction (creatinine > 1 mg/dL), 73 (6.5%) isolated liver dysfunction (bilirubin > 1 mg/dL), and 207 (18.5%) coexisting dysfunction of the kidneys and the liver (both creatinine and bilirubin > 1 mg/dL). The percentage of patients with elevated MELD-XI score remained constant through a 60 day follow-up, as we observed a gradual decrease of liver dysfunction prevalence, counterbalanced by an increase in renal dysfunction. Serelaxin treatment was associated with a lower MELD-XI score on Day 2 and Day 5 (both P

Congestion is a common cause of clinical deterioration and the most common clinical presentation at admission in acute heart failure (HF). Therefore, finding effective and sustainable ways to alleviate congestion has become a crucial goal for treating HF patients. Congestion is a result of complex underlying pathophysiology; therefore, it is not a direct cause of the disease but its consequence. Any therapy that directly promotes sodium/water removal only, thus targeting only clinical symptoms, neither modifies the natural course of the disease nor improves prognosis. This review aims to provide a comprehensive evaluation of the current decongestive therapies and propose a new (not diuretic‐centred) paradigm of long‐term congestion management in HF that attempts to correct the underlying pathophysiology, thus improving congestion, preventing its development, and favourably altering the natural course of the disease rather than merely treating its symptoms.

Comprehensive uptitration of neurohormonal blockade targets fundamental mechanisms underlying development of congestion and may be an additional approach for decongestion after acute heart failure (AHF). This hypothesis was tested in the STRONG-HF (Safety, Tolerability, and Efficacy of Rapid Optimization, Helped by N-Terminal Pro–Brain Natriuretic Peptide Testing of Heart Failure Therapies) trial. In STRONG-HF, patients with AHF were randomized to the high-intensity care (HIC) arm with fast up-titration of neurohormonal blockade or to usual care (UC). Successful decongestion was defined as an absence of peripheral edema, pulmonary rales, and jugular venous pressure <6 cm. At baseline, the same proportion of patients in both arms had successful decongestion (HIC 48% vs UC 46%; P = 0.52). At day 90, higher proportion of patients in the HIC arm (75%) experienced successful decongestion vs the UC arm (68%) (P = 0.0001). Each separate component of the congestion score was significantly better in the HIC arm (all, P < 0.05). Additional markers of decongestion also favored the HIC: weight reduction (adjusted mean difference: −1.36 kg; 95% CI: −1.92 to −0.79 kg), N-terminal pro–B-type natriuretic peptide level, and lower orthopnea severity (all, P < 0.001). More effective decongestion was achieved despite a lower mean daily dose of loop diuretics at day 90 in the HIC arm. Among patients with successful decongestion at baseline, those in the HIC arm had a significantly better chance of sustaining decongestion at day 90. Successful decongestion in all subjects was associated with a lower risk of 180-day HF readmission or all-cause death (HR: 0.40; 95% CI: 0.27-0.59; P < 0.0001). In STRONG-HF, intensive uptitration of neurohormonal blockade was associated with more efficient and sustained decongestion at day 90 and a lower risk of the primary endpoint. [ABSTRACT FROM AUTHOR]

Aims: Biologically active adrenomedullin (bio‐ADM) is a promising marker of residual congestion. The STRONG‐HF trial showed that high‐intensity care (HIC) of guideline‐directed medical therapy (GDMT) improved congestion and clinical outcomes in heart failure (HF) patients. The association between bio‐ADM, decongestion, outcomes and the effect size of HIC of GDMT remains to be elucidated. Methods and results: We measured plasma bio‐ADM concentrations in 1005 patients within 2 days prior to anticipated discharge (baseline) and 90 days later. Bio‐ADM correlated with most signs of congestion, with the exception of rales. Changes in bio‐ADM were strongly correlated with change in congestion status from baseline to day 90 (gamma −0.24; p = 0.0001). Patients in the highest tertile of baseline bio‐ADM concentrations were at greater risk than patients in the lowest tertile for the primary outcome of 180‐day all‐cause mortality or HF rehospitalization (hazard ratio [HR] 2.14, 95% confidence interval [CI] 1.42–3.22) and 180‐day HF rehospitalization (HR 2.33, 95% CI 1.38–3.94). Areas under the receiver‐operating characteristic curves were 0.5977 (95% CI 0.5561–0.6393), 0.5800 (95% CI 0.5356–0.6243), and 0.6159 (95% CI 0.5711–0.6607) for bio‐ADM, N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) and their combination, respectively, suggesting that both bio‐ADM and NT‐proBNP provided similarly modest discrimination for this outcome. A trend towards better discrimination by combined bio‐ADM and NT‐proBNP than NT‐proBNP alone was found (p = 0.059). HIC improved the primary outcome, irrespective of baseline bio‐ADM concentration (interaction p = 0.37). In contrast to NT‐proBNP, the 90‐day change in bio‐ADM did not differ significantly between HIC and usual care. Conclusions: Bio‐ADM is a marker of congestion and predicts congestion at 3 months after a HF hospitalization. Higher bio‐ADM was modestly associated with a higher risk of death and early hospital readmission and may have added value when combined with NT‐proBNP. [ABSTRACT FROM AUTHOR]

Aims: Inflammation has emerged as a potential key pathophysiological mechanism in heart failure (HF) in general and acute HF (AHF) specifically, with inflammatory biomarkers shown to be highly predictive of adverse outcomes in these patients. The CORTAHF study builds on both these data and the fact that steroid burst therapy has been shown to be effective in the treatment of respiratory diseases and COVID‐19. Our hypothesis is that in patients with AHF and elevated C‐reactive protein (CRP) levels without symptoms or signs of infection, a 7‐day course of steroid therapy will lead to reduced inflammation and short‐term improvement in quality of life and a reduced risk of worsening HF (WHF) events. Methods and results: The study, which is currently ongoing, will include 100 patients with AHF ages 18–85, regardless of ejection fraction, screened within 12 h of presentation. Patients will be included who have NT‐proBNP > 1500 pg/mL and CRP > 20 mg/L at screening. Exclusion criteria include haemodynamic instability and symptoms and signs of infection. After signed consent, eligible patients will be randomized according to a central randomization scheme stratified by centre 1:1 to either treatment once daily for 7 days with 40 mg prednisone orally or to standard care. Patients will be assessed at study day 2, day 4 or at discharge if earlier, and at days 7 and 31 at the hospital; and at day 91 through a telephone follow‐up. The primary endpoint is the change in CRP level from baseline to day 7, estimated from a mixed model for repeated measures (MMRM) including all measured timepoints, in patients without a major protocol violation. Secondary endpoints include the time to the first event of WHF adverse event, readmission for HF, or death through day 91; and changes to day 7 in EQ‐5D visual analogue scale score and utility index. Additional clinical and laboratory measures will be assessed. Conclusions: The results of the study will add to the knowledge of the role of inflammation in AHF and potentially inform the design of larger studies with possibly longer duration of anti‐inflammatory therapies in AHF.

Aims: We aim to identify the most accurate marker for early prediction of poor diuretic response in acute heart failure (AHF) patients with signs of congestion requiring intravenous diuretic treatment. Methods: In this single‐centre, prospective observational study, AHF patients with signs of congestion received a standardized intravenous furosemide dose (1 mg/kg of body weight; 40 mg in bolus and remaining dose in 2 h continuous infusion). Subsequently, we assessed spot urine composition at 2 h post‐administration, comparing it with total urine output at 6 h. Various potential urine markers were analysed for predicting urine output using receiver operating characteristic (ROC) curves and logistic regression models. We investigated guideline‐recommended markers, including spot urine sodium (UNa+) and its cut‐off, and introduced the UNa+/UCr (urine creatinine concentration) ratio adjusting UNa+ for urine dilution. Results: Out of 111 patients (85% males, 66.4 ± 13.9 years old, NTproBNP 7290 [4493–14 582] pg/ml), there were 18 (16%) with a poor diuretic response (cumulative urine output <600 ml during the first 6 h). The mean 6 h cumulative diuresis in patients with poor and good diuretic response was 406 ± 142 and 2114 ± 1164 ml, respectively, P < 0.005. After an initial evaluation of several potential biomarkers, only UNa+, UCr and UNa+/UCr were selected as candidates with the highest predictive value. The cut‐off for UNa+ adjusted for urine dilution: UNa+/UCr ratio <0.167 mmol/mg × 10−1 was determined by ROC analysis with the highest area under the curve (95% confidence interval): 0.956 (0.915–0.997), P < 0.001. When compared with the guideline‐recommended cut‐off (UNa+ <50 mmol/L as a reference, specificity—0.97; sensitivity—0.83), the odds ratio (OR) for UNa+/UCreat to identify a poor diuretic response was 2.5 times greater, regardless of kidney function (OR for estimated glomerular filtration rate in the logistic regression model was 0.978 [0.945–1.013, P = 0.222]). Conclusions: The UNa+/UCr ratio in a spot urine sample 2 h after intravenous diuretic administration is a simple, highly predictive marker for the identification of AHF patients with poor diuretic response, surpassing guidelines‐recommended markers like UNa+.

Heart failure (HF) affects more than 60 million individuals globally. Empagliflozin is currently approved for type 2 diabetes and chronic HF. Clinical trials have demonstrated that empagliflozin reduces the composite end point of hospitalizations for HF and mortality and improves the quality of life irrespective of left ventricular ejection fraction. Empagliflozin is a once-daily medication with minimal drug–drug interactions and does not require titration. Empagliflozin causes mild weight loss and does not significantly reduce blood pressure. Empagliflozin acts as an enabler for other HF drugs by reducing the risk of hyperkalemia. Empagliflozin is also beneficial for chronic kidney disease which exists commonly with HF. This review outlines the pharmacokinetics, pharmacodynamics, safety, and efficacy of empagliflozin in HF across various sub-groups and settings. Empagliflozin is a one-daily medication and is an effective glucose-lowering drug for the treatment of diabetes. In recent years, researchers and medical professionals have discovered that empagliflozin may also be used to treat some cardiovascular conditions. Numerous people suffer from myocardial infarction ('heart attack') each year. According to several clinical trials, empagliflozin may slow the course of myocardial infarction and improve clinical outcomes and quality of life. Additionally, empagliflozin does not result in a substantial decrease in blood pressure and can also lead to mild weight loss. Therefore, empagliflozin shows potential as a useful medication for the treatment of myocardial infarction, especially in individuals with diabetes and impaired kidney function. Article highlights Pharmacokinetics & metabolism Empagliflozin is a once-daily medication and does not require titration, unlike other heart failure (HF) medications. There are currently no reports of suspected drug–drug interactions involving empagliflozin. Pharmacodynamics Empagliflozin induces a natriuretic effect, improves myocardial ischemia-reperfusion injury, and reduces infarct size. Pharmacodynamics Empagliflozin causes mild weight loss, acts as an enabler for other HF drugs by reducing the risk of hyperkalemia, and has been linked to a rise in mean left ventricular ejection fraction. Empagliflozin is also beneficial for chronic kidney disease that frequently coexists with HF. Clinical efficacy Empagliflozin reduces the risk of cardiovascular mortality and hospitalization for HF regardless of the baseline systolic blood pressure, the spectrum of HF risk, type 2 diabetes status, background diuretic use, and baseline ejection fraction status.

Central Illustration. Abbreviation: RSV – Respiratory Syncytial Virus. [Display omitted] • Simultaneous vaccination against RSV and Influenza virus among high-risk heart failure patients is safe. • Only small percentage of patients experienced reactions severe enough to prevent daily activities. • Simultaneous vaccination reduces patients contact with healthcare. The safety of simultaneous vaccination for Respiratory Syncytial Virus (RSV) and influenza in vulnerable high-risk heart failure (HF) patients remains unclear. In an open-label, prospective study, 105 patients received concurrent influenza (Vaxigrip Tetra, season 2023/2024, Sanofi) and RSV (Arexvy, GSK) vaccinations from September 15th to November 17th, 2023. Adverse events were collected on the fourth-day post-vaccination. Overall, the vaccination was well tolerated, with the most common reaction being injection site pain (63 %). General symptoms occurred in 33 % of patients, predominantly fatigue (23 %), myalgia (12 %), and headache (9 %). Grade 3 reactions were observed in 6 % of patients, and a few experienced temperature elevation or flu-like symptoms, managing them with antipyretics. Notably, there were no exacerbations of HF, hospitalizations, or deaths within a week post-vaccination. This study indicates the safety of simultaneous influenza and RSV vaccination in high-risk HF patients, with a low incidence of mild adverse events. [ABSTRACT FROM AUTHOR]

Aim: The EMPULSE (EMPagliflozin in patients hospitalised with acUte heart faiLure who have been StabilizEd) trial showed that, compared to placebo, the sodium–glucose cotransporter 2 inhibitor empagliflozin (10 mg/day) improved clinical outcomes of patients hospitalized for acute heart failure (HF). We investigated whether efficacy and safety of empagliflozin were consistent across the spectrum of left ventricular ejection fraction (LVEF). Methods and results: A total of 530 patients hospitalized for acute de novo or decompensated HF were included irrespective of LVEF. For the present analysis, patients were classified as HF with reduced (HFrEF, LVEF ≤40%), mildly reduced (HFmrEF, LVEF 41–49%) or preserved (HFpEF, LVEF ≥50%) ejection fraction at baseline. The primary endpoint was a hierarchical outcome of death, worsening HF events (HFE) and quality of life over 90 days, assessed by the win ratio. Secondary endpoints included individual components of the primary endpoint and safety. Out of 523 patients with baseline data, 354 (67.7%) had HFrEF, 54 (10.3%) had HFmrEF and 115 (22.0%) had HFpEF. The clinical benefit (hierarchical composite of all‐cause death, HFE and Kansas City Cardiomyopathy Questionnaire total symptom score) of empagliflozin at 90 days compared to placebo was consistent across LVEF categories (≤40%: win ratio 1.35 [95% confidence interval 1.04, 1.75]; 41–49%: win ratio 1.25 [0.66, 2.37)] and ≥50%: win ratio 1.40 [0.87, 2.23], pinteraction = 0.96) with a favourable safety profile. Results were consistent across individual components of the hierarchical primary endpoint. Conclusion: The clinical benefit of empagliflozin proved consistent across LVEF categories in the EMPULSE trial. These results support early in‐hospital initiation of empagliflozin regardless of LVEF. [ABSTRACT FROM AUTHOR]
